exploring iso settings:
1. What are the three parts of the exposure triangle? lens aperture, shutter speed and ISO.
2. How much more exposure is there as you change from one ISO setting to the next? Each ISO setting is double the one before: if you increase the ISO from 100 to 200, you double the camera's sensitivity
3. What is the main drawback to changing the ISO from low to high? Increasing the ISO to 3200 gives much more noise, but it's still not too obtrusive at normal viewing distances and it allows a shutter speed that should eliminate any camera shake, especially if your lens has VR built in.
4. What are a few ways to reduce the appearance of noise in the photo? each, chromatic and luminance noise can be reduced using different tools during the editing stage. These are often provided as separate noise-reduction sliders by a raw converter (such as in Adobe Photoshop's Camera Raw utility).
5. What is the difference between Chromatic and Luminance noise? Luminance appears to look like grains of sand, meanwhile Chromatic noise is colored and looks like the rainbow-like sheen when looking at a patch of oil
6. What are a couple of example of when and why you might want to increase the ISO of the camera? increase the ISO if you're shooting in marginal conditions (or use your camera's Auto ISO function). As well as, If your DSLR has a full auto mode, it will make these decisions for you, increasing the ISO where it has to in order to avoid camera shake.
